SHIPPING-CAN.

Specification of Letters Patent.

Patented Nov. 30, 1915.

Application filed August 19, 1914. Serial No. 857,586.

1o all whom it may concern Be it known that I, lVAL'rna E. PERKINS, citizen of the United States, residing at Baker, in the county of Baker and State of Oregon, have invented new and useful Im provements in Shipping-Cans, of which the following is a specilication.

This invention relates to shipping cans, and particularly to a can for shipping live fish; and it has for its object the provision of an outer vessel and an inner refrigerant container, the latter being in open communication with the former and having its walls spaced therefrom so as to provide an intervening storing chamber and to permit of its initially accommodating water under a prescribed*temperature, the communication of the refrigerant container and the outer vessel being such that the temperature of the water will lower during shipment of the can and the fish thereby maintained in a refrigerated condition.

lVith the above and other objects in view, the invention consists of certain novel features of construction, combination and ar rangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings z-Figure 1 is a vertical section through the can; Fig. 2 is a horizontal section on line 2-2 of Fig. 1; Fig. 3 is a horizontal section on line 3-3 of Fig. 2; and Fig. l is a section through a portion of the can, showing a slightly modified form of the invention.

The can comprises an outer vessel of cylindrical form as herein illustrated provided with a fixed bottom 2, a crown 3, a vertical wall 4c rising from the crown, and an outwardly flared mouth 5 extending into the walls Vof the latter and adapted to be frictionally engaged by correspondingly flared walls 6 upon the vertical flange 7 of a closure S. The closure 8 is adapted to be inserted into the neck of the vessel l and to be held confined therein by means of a seal 9 which may be passed through alined perforations 10 and 11 in the flanges 5 and 6.

Within the vessel 1 is a refrigerant container 12 having vertical Walls spaced from the adjacent vertical walls of the vessel 1. This container has its bottom closed horizontally by the bottom 2 of the vessel 1 and directly'above said bottom 2 the vertical walls of the container 12 are provided with lateral passages 13, which are partly closed by foraminous members 14, the latter being soldered or otherwise suitably secured to the container. At the upper end, the container 12 is provided with a crown 15, a vertical neck 16 and flared walls 17, which extend outwardly from the neck. The container 12 is located centrally of the vessel l and the upper end of the container is located below the plane of the crown 3 of the vessel and is connected therewith by means of diagonal braces 1S, the lower ends of which being riveted or otherwise suitably secured as at 19 to the flange 17 and secured in a similar manner, as at 20, at their upper ends to the crown. A suitable closure 21 of a diameter which will permit of its being freely passed through the neck of the vessel l is employed for closing the upper end. of the container 12.

From the construction described, it is evident that a small quantity of water can be placed in the storage space between the refrigerant container 12 and the outer vessel 1 and the fish placed therein and ice placed in the container, and then a small quantity of water placed thereon so that the temperature of the latter will be lowered and the water from the container then permitted to discharge and circulate in the storage space between the container and the outer vessel and the temperature of the water in the storage space gradually lowered.

In the modified form of the invention shown in Fig. 3, the can is designed for the shipment of milk and is shown to include an outer vessel 1a and an inner vessel 1", the latter being similar in construction to the refrigerant container 12, but as illustrated the bottom and adjacent portions thereof are wholly impervious, so that liquid placed in the space B between the inner and outer vessel will be confined against circulating in the inner vessel. In this form of the invention the space B may be used as a storage chamber or a refrigerant container, as may be found most desirable.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention as claimed.'

Having thus described 1ny invention, what claim is:-

Ashlpplng can comprising inner andV outer cylindrical Vesselsof different heights, a neck provided With a horizontal iange attaching it to the outer Vessel, the inner and outervessels being spa-ced laterally to provide a storage chamber therebetween, the chamber opening directly into the neolof vthe outer vessel, elosuresifor the inner and 10 WALTER E.
